SOVERSION — CMake 3.16.2 Documentation

# SOVERSION

What version number is this target.

For shared libraries `VERSION` and `SOVERSION` can be used to specify the build version and API version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so-names. If only one of both is specified the missing is assumed to have the same version number. `SOVERSION` is ignored if `NO_SONAME` property is set.

## Windows Versions

For shared libraries and executables on Windows the `VERSION` attribute is parsed to extract a `<major>.<minor>` version number. These numbers are used as the image version of the binary.

## Mach-O Versions

For shared libraries and executables on Mach-O systems (e.g. macOS, iOS), the `SOVERSION` property corresponds to compatibility version and `VERSION` to current version. See the `FRAMEWORK` target property for an example. Versions of Mach-O binaries may be checked with the `otool -L <binary>` command.
